From our About page

Brand new Citizen Tsuyosa Small Second NK5010-51L with automatic Caliber 8322, 60 h power reserve, blue sunray dial with small seconds sub-dial, sapphire crystal, 40 mm steel case and bracelet, and 50 m water resistance.

The Citizen Tsuyosa Small Second NK5010-51L is a stylish Japanese automatic watch blending contemporary design with reliable mechanical performance. Part of the new Tsuyosa series, this reference features a 40 mm stainless steel case with a subtly recessed crown at 4 o’clock, giving it a sleek and modern profile that wears easily on most wrists. The textured blue sunray-brushed dial includes a small seconds sub-dial at 6 o’clock for classic mechanical charm, along with luminous hands and applied indices for strong legibility.

Underneath the sapphire crystal sits the Citizen Caliber 8322 automatic movement, an in-house mechanical engine with a 60-hour power reserve, a significant upgrade over entry-level automatic watches and a clear selling point in this segment. The robust movement winds via wrist motion and features a transparent case back for a glimpse of the mechanical rotor in action.

The integrated stainless steel bracelet with a secure butterfly clasp completes the look with comfort and durability. With 50 m / 5 bar water resistance, this watch is suited for daily wear and light splashes, making it a versatile choice for both casual and smarter occasions.
